Patented Feb, 24, 1920.

Application filed-February 12,1919. SerialNo. 276,617.

To all whom) it 'lnay concern 7 Be it known that I, RICHARD S. GIESE, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and have invented a new State of Pennsylvania,

of which and useful Electric-Light Fixture, the following is a Specification. This invention has. reference light fixtures, and its objectis to provide a combined ceilingbowl and shade attachable to the wall by a single fastening device and arranged to holda cluster of'electric lamps which may be set'ina'nd sustainedby the bowl without any carrying fixture other than thebowl itself.

In accordance with the invention, the

bowl is a one-piece structure of glass open only where engaging the ceiling and pro- .vided with a cluster or group of protrusions or shades each suitably shaped and proportioned to hold an electric light bulb with a socket carrying the bulb located in the bowl but unattached to any bracket or sustaining device. Centrally traversing Moreover, aside from a-small sustaining pipe or rod centralized withrespect to the bowl, no metallic parts whatever are employed, therlanrps and sockets not being considered. Furthermore, by utilizing a ceiling outlet or the sustaining member, which maybe a pipe, the lamps and sockets are merely loosely mounted in the shades forming pendentparts of the bowl. and con stituting the cluster.

The invention will be best understood from a considerationofthe followingde-' tailed description taken in connection with the accompanying drawing forming'part of this specification, with the understanding, however, that the'invention is not confined to any strict conformity with the showing of. the drawing, but may bechanged and lnpdified so long as such changes and. mod1-.

to electric fications mark no material departure from the sallentfeatures of the invention as expressed in the appended claims.

In the drawing wFigure 1 isa d1 elevation. I

Fig. 2 is aibottom plan view of the structure shown in Fig. 1.

Referring to the drawing, there isshown a bowl 1 which may correspond 'in general shape to ceiling or other bowls used in electric light fixtures, and the bowl is open at the upper. end and provided with a marametric section of the. [electric light fixture, with some parts in ginal bead2 which, in accordance with the invention, is designed to directly engage against the ceiling of a room. The bowl has a rounded bottom portion which may be of customary shape, and at intervals on the bottorn' portion near the sides of the ends, although this particular shape is by no means obligatory. The pendent portions 3 open directly into the interior ofthe bowl and constitute shades for housing electric lamp 4 which latter-are provided with sockets 5 of ordinary construction The body ofthebowl and the major portion of the pendent projections 3 are formed of frosted or milk glass, or in fact any type of, glassof a lightedistri'butive nature. The

' bowl are pendent projections 3 which are shown as slightly tapering toward the lower bottom portion of each "pendent shade 3 is of clear glass, as shown at 6, or this por- ,tion of the shademay be of any character of a nature permitting more brilliant illumination directly beneath the fixture or bowl than 1s provided by the remainder of the material of which the bowl is made. The entire bowl including the pendent projec- 'tions is of one-piece construction, and while the bowl may be as ornamental as desired, it may be formed of, so far as its light diffusive characteristics. are concerned, one

character throughout, except at the bottoms. of the pendent projections where the arrangement is-such that there is neither material impediment to nor difi'usion of light. Secured to the ceiling of the room in which the fixture is to be installed, is a I pendent rod 7 which may be either a solid rod or a pipe, and the bowl 1 has a centralized opening S-thrOugh-Which the rod or pipe 7 projectsand, 'where projecting, the pipeor rod 1 port-ion 9. Applied to the threaded portion 7 has an exteriorly threaded 9 is a nut or knob 10 which may be of any suitable ornamental form engaging and sustaining the bowl and holding the head 2 against the ceiling of the room with suflicient firmness to prevent displacement of v the bowl.

The sockets 5 have electric conductors 11.

attached thereto, and these conductors may drawingor in any suitablemanner, and this" bowl with the lamps therein after the conductors 11 have been properly coupled up to the mains, is placed againstthe ceiling in Such .m'anner that thepipe or sustaining member 7 projects through the passage 8, after which the nut 10 is applied to secure the bowl directly against the ceiling.

With the fixture of the, invention all metal rings, chains, etc, may beeliminatedand the bowl may be installed directly against theceiling, thus sealing the interior of the bowl against entrance of dust and dirt. Of course sustaining chains might be employed and certain advantages offthe fixture retained, but withthe loss of other advantages. It'is unnecessary with the bow] constructed as described to provide any metallic supports for thelamps, and'this' is made possible by the fact that the bowl and pendent shades are either vfrosted or made of inilkglass orthc like, thereby producing a diffusion of the light to hide direct Vision of the lamps and distributing the illumination. While the bottoms of the shades do not have to be made of clear glass it is preferable'that they should be somade. Nor is it necessary that the bowl and shades or the shades forming part of the bowl be made of frosted, or milk, or opaque glass. In fact the bowl and shades may be made of any appropriate kind of glass, which may also form the bottoms of the shades.

Essential features of the invention are the formation of the bowl and shades of one piece of glass and, in the simpler forms, the bowl is held flush up against'tl'ie ceiling with the shades pendent and all metal parts elimihated, the sustaining member 7 which may be conveniently made of iron pipe, and the nut or knob 1.0 which, because exposed to View, may be made of brass or some other suitable material.
